Important Issues for Benchmarking
What is benchmarking
Benchmarking is an important tool we use to access the relative performance of a software or specific component of a software, normally by running a number of standard tests and trials against it.

ifunc - GNU Indirect Function
ifunc General Idea:
ifunc is a special feature provided by GNUC which can help you to optimize your function call. It allows to create multiple implementations of one function. A best implementation can be selected during runtime for particular procesor.

Software Optimization - Building Software
Building Software
This week we are going to discuss how to build a software. I need to learn more about it because I am going to try optimizing an open source package/library. In order to work with it, at least I need to build it successfully firstly. So let us take a look about the modern software building process.

OpenCV Optimization Practice - Stage I
OpenCV Optimization - Stage I
After some experience of previous software optimization practices, I decide to play with to a very popular computer vision library - OpenCV to see whether the optimization skills I learned before can make a little bit improvement to a real-world project.
